Agreed with Fed, ATP has slowed down everything and anything and that's not fair for a lot of players who like it faster (Fed, Hewitt, Delpo, Roddick etc etc).
A quote from Fed in Brisbane:
“I like it a bit faster, to be honest. It’s just nice when the slider drags a bit or the slice stays a bit lower and guys don’t just eat it up, even though it's a decent slice. So I think it's a good thing that it’s a bit faster here.â€

This is why players don't chip and charge no more, when advantage has gone towards those who hit passing shots. Too much time for them to pick where they want to pass, so volleyers are at a great disadvantage to start with. Sure grass is still grass and hardcourt is hardcourt which are still faster than clay, but they are too slow compared to years ago. Fed had a lot of potential to play S&V and improve on that part like he did in the early 2000s, but he also knew the advantage got skewed towards baseliners so he kind of became one of those 'grinders' himself, camping at the baseline.... although he was still very aggressive with it.
Don't know who made the decision to slow it down so much, but he is simply not fit for his job.
